Probably the least unoriginal songs are my favourites, the Halo Theme Mjolnir Mix - I will never forget walking out onto the walkways with the Marines chasing the Scarab, hearing that song kicking in and getting pumped to fight the Covie's on board.

My second favourite is Blow me Away by BB, but this is simply because i've always liked the band and the song when it played in the Mausoleum of the Arbiter again fit the mood. You knew **** was about to go down.
